I have been using it for a long time. It has helped me a lot in transferring text to my mobile (Nokia 5230, non IOS or Android), via QR reader.
I transfer big text of SMS (festival, birthday etc. wishes) from searched sites, url of a site to check in mobile browser etc. I found it much master to type my required text in the QR box and then QR read it in my mobile.
Really a time saver.
